Leaves curling up/down weird colors

Leaves curling upwards is usually a sign of heat or light stress though I think your problem is more PH related or at worst a root problem it does not look like a toxcity your medium looks nice and dry so over watering is not an issue I think you should give her some ph balanced water and if you can mesure the run off and see whats going on there :) I always say when in doubt flush it out :) what are your RH levels at are they low ? That could also be a contributor. Anyway Im sure she will be okay just keep up the great work maybe put the light higher add more air flow if you can try bring the temps down abit :) 👊
